Project A and Project B have a cost of $30,000,000 today. Project A will have cash flows of $12,000,000 per year for three years, while Project B will have cash flows of $15,000,000 the first year, $10,000,000 the second year, and $11,000,000 the third year. 

Calculate the NPV and the IRR for Project A using a 10% cost of capital and show your work by using TWO of the following methods: (1) using the formula, (2) identifying all variables using the calculator’s function keys, (3) using the steps on the calculator to calculate NPV and IRR.
